A MSI controller of LS1043a v1.0 only includes one MSIR and is assigned one GIC interrupt. In order to support affinity, LS1043a v1.1 MSI is assigned 4 MSIRs and 4 GIC interrupts. But the MSIR has the different offset and only supports 8 MSIs. The bits between variable bit_start and bit_end in structure ls_scfg_msir are used to show 8 MSI interrupts. msir_irqs and msir_base are added to describe the difference of MSI between LS1043a v1.1 and other SoCs.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
